With reference again to FIGS. 2-4 and 6-9, the fan support 82 are operably coupled with the lower wall 28 of the upper thoracic region 20 and also coupled with first and second angled supports 130, 132. Each of the first and second angled supports 130, 132 extends into the intermediate space 122 of the upper thoracic region 20 and each includes an undulating or sinusoidal configuration. This construction allows for flexibility and movement of the fan support 82 to accommodate the different weights of users and also different postures and loads that can affect the seatback 12. As previously noted, the bottom portion 26 of the upper thoracic region 20 includes the lower wall 28, which has an undulating or sinusoidal configuration. Notably, the undulating or sinusoidal configuration of the lower wall 28 of the upper thoracic region 20 undulates in a plane generally parallel with the seating surface 51 of the seat 52. Accordingly, the undulations extend forward and rearward relative to the seatback surface 53. The upper portion 38 of the lower lumbar region 32, and more specifically, the upper wall 40 of the lower lumbar region 32 includes a sinusoidal configuration as well. The sinusoidal configuration of the upper wall 40 of the lower lumbar region 32 also undulates forward and rearward relative to the seatback 12. It will be understood that the carrier 18 is generally curved to complement the shape of the back of an occupant. More specifically, the upper thoracic region 20 is shaped to generally cradle and support the upper back of an occupant, while the lower lumbar region 32 is designed to cradle and support the lower back of an occupant.

With reference now to FIG. 5, in the illustrated embodiment, the seatback 12 of the vehicle seating assembly 10 includes the following seat cushion components. The seat frame 56 is connected with the seat 52 and provides general structural support to the occupant. The back panel 14 is connected with a rear portion of the seatback frame 57. The head restraint 92 is disposed above the seatback frame 57 and is operably coupled therewith. The head restraint 92 may include a variety of functions, including forward and rearward motion, as well as upward and downward motion, to better support the head of an occupant. In addition, the vehicle seating assembly 10 includes an upper thoracic support 116 that is adjustable between forward and rearward positions. The upper thoracic support 116 is located in front of the front closeout panel 16 and includes connection features 112. The front closeout panel 16 includes an upper portion 156 and a lower portion 158. The upper portion 156 of the front closeout panel 16 wraps around a front portion of the seatback frame 57 and couples with the hard back panel 14. The lower portion 158 of the front closeout panel 16 engages with a lower portion of the seatback frame 57 and engages a lower portion of the hard back panel 14. The peripheral gap 24 is defined between the upper portion 156 of the thoracic support 116 and the front closeout panel 16. The peripheral gap 24 is also located between the lower lumbar region 32 and the lower portion 158 of the front closeout panel 16. First and second side support members 164, 166 are configured to be fastened with sides of the carrier 18. The entire carrier 18, as well as first and second side support members 164, 166, are designed to engage the upper portion 156 and the lower power 158 of the front closeout panel 16. At the same time, the carrier 18 supports the cushion assembly 55 and the coverstock 74. The cushion assembly 55 may be operably coupled with the coverstock 74 via a glue or adhesive, or via fasteners configured to engage the front of the cushion assembly 55, as previously disclosed.

With reference now to FIGS. 6-10, 15 and 16, the carrier 18 includes openings 170 on each side of the lower lumbar region 32. The openings 170 are designed to receive engagement features 172 on each of the first and second side support members 164, 166. In addition, a lower protuberance 174, which extends in a forward direction, is configured to engage an aperture 176 having peripheral slots 178 that deflect to allow the lower protuberance 174 to be received within the aperture 176. The aperture 176 is configured to receive the protuberance 174 and secure the same such that the first and second side support members 164, 166 can be retained on the carrier 18. In addition, a second lower protuberance 180 is disposed below the protuberance 174, and is configured to engage a lower aperture 182 on the carrier 18. The lower aperture 182 also includes peripheral slots 184 that deflect to allow the lower aperture 182 to receive the second lower protuberance 180. Each of the protuberances 174, 180 maintain the first and second side support members 164, 166 in secure abutment with the carrier 18. In addition, an upwardly turned hook 190 is disposed on an upper portion of each of the first and second side support members 164, 166. The upper hook securely engages an engagement wall 192 on a forward side of the carrier 18. It will be understood that the first and second side support members 164, 166 are mirror images of one another.

With reference now to FIGS. 12-14, various undulating or sinusoidal configurations of portions of the carrier 18 are illustrated. FIG. 12 illustrates an undulating or configuration that extends along the first and second angled supports 130, 132. The undulating configuration that extends along the first and second angled supports 130, 132 allows flexibility of the fan support 82 such that the fan support 82, or a fan disposed therein, does not provide for an uncomfortable projection into the back of a passenger. In addition, the first and second angled supports 130, 132, and the sinusoidal configuration of the first and second angled supports 130, 132, allow for flexible movement of the fan support 82 relative to the already flexible carrier 18. FIG. 13 illustrates the sinusoidal configuration across the lower wall 28 of the upper thoracic region 20. The sinusoidal configuration allows for flexible movement of the upper thoracic region 20 relative to the lower lumbar region 32. The lower wall 28 of the upper thoracic region 20 is operably coupled with the upper wall 40 of the lower lumbar region 32 via the concave connectors 42. Accordingly, flexibility in both lateral and vertical directions is provided. For even additional flexibility, the sinusoidal configuration is provided in the upper wall 40 of the lower lumbar region 32, as shown in FIG. 14. It will also be noted that a periphery of the upper thoracic region 20 and lower lumbar region 32 includes a rearwardly opening slot 210 configured to receive trim stock fasteners that secure a trim stock to a rear portion of the carrier 18.

With reference to FIGS. 17 and 18, the illustrated embodiment shows the configuration of the protuberances 174, 180 relative to the apertures 176, 182, respectively. As illustrated, an inner wall 194 that defines the apertures 176, 182 is canted or angled on a side of the apertures 176, 182 to provide an easier snap fit connection with the protuberances 174, 180. This construction has the added benefit of maintaining a more secure connection between the protuberances 174, 180 and the apertures 176, 182. The cant or angled wall portion is specifically sized and fitted to retain the protuberances 174, 180 during use.

With reference now to FIGS. 8-12, as well as FIGS. 19 and 20, a base wall in the form of a lower cross-member 200 of the carrier 18 includes lateral elongate slots 202. The elongate slots 202 are configured to receive engagement features in the form of retention tethers 204 that include a securing member 206 and a flexible band 208 connected to the securing member 206. The flexible band 208 may be secured with the cushion assembly 55 or the coverstock 74 and may be elastic in nature, allowing for expansion and contraction. The retention tethers 204 provide a releasable yet reliable engagement of the cushion assembly 55 with the carrier 18 (FIGS. 19 and 20).

With reference now to FIGS. 21 and 22, upper corners 230 of the carrier 18, and more specifically of the upper thoracic region 20 of the carrier 18, include a generally planar portion with a fastener receiving aperture 234. The fastener receiving aperture 234 includes slots configured to accommodate a mechanical fastener engaging the fastener receiving aperture 234. The fastener receiving aperture 234 includes a generally semicircular construction with slots 236 extending therefrom. In the illustrated embodiment, the slots 236 extend approximately 120 degrees from one another. However, it will be understood that the slots 236 may extend at any angle relative to one another, and may be more than or less than three slots 236 that extend from the fastener receiving aperture 234.

With reference now to FIGS. 23-25, the illustrated carrier 18 includes a plurality of integrated trim attachment features and tension features for use with the cushion assembly 55 that is supported on the carrier 18. These features aid in comfort and aid in assembly during manufacture. The carrier 18, and specifically the upper thoracic region 20 of the carrier 18, includes a plurality of peripheral trim retainers 304 that are adjacent the peripheral support 34 and which retain a trim cover. The plurality of peripheral trim retainers 304 include an elongate inwardly-extending tab 306. The inwardly-extending tab 306 is configured to engage a slot or other attachment feature of the trim cover. Notably, the plurality of peripheral trim retainers 304 are disposed both on the upper thoracic region 20 as well as the lower lumbar region 32. In the illustrated embodiment of FIGS. 23 and 24, the peripheral trim retainer 304 is disposed on each side of the lower lumbar region 32 spaced slightly from the peripheral edge 98. Two peripheral trim retainers 304 are disposed on each side of the upper thoracic region 20 directly adjacent the peripheral edge 98. As shown in FIG. 26, the elongate inwardly-extending tab 306 is disposed on a periphery of the upper thoracic region 20 and the lower lumbar region 32, and includes a tapered or rounded forward edge 308 to ease in coupling the trim cover with the peripheral trim retainer 304. Additionally, it should be noted that, as shown in FIGS. 23 and 25, the peripheral trim retainers 304 on the upper thoracic region 20 extend directly from the peripheral edge 98 inwardly.

Referring again to FIG. 23 and also referring to FIG. 25, the lower lumbar region 32 also includes at least one straight edge tie-down 320 that is adjacent the opening 170 defined by the lower lumbar region 32. The straight edge tie-downs 320 interact directly with the cushion assembly 55, the coverstock 74, or a combination thereof, or another feature coupled with the coverstock 74 or the cushion assembly 55 to secure the same to the carrier 18. At the same time, the opening 170 defined by the lower lumbar region 32 is maintained open so that air can be moved into and out of the carrier 18. The straight edge tie-down 320 also includes an aperture 322 at a lower end 324 thereof configured to receive a tie, string, clip, etc. to maintain the cushion assembly 55 in abutting contact with the carrier 18.

Referring now to FIGS. 23, 27, and 28, inner trim retainers 330 each include first and second forwardly-extending barbed hooks 332, 334. As illustrated in FIG. 27, the first and second forwardly-extending barbed hooks 332, 334 extend forward and face toward one another. The first and second forwardly-extending barbed hooks 332, 334 are configured to receive a complementary engagement member extending rearwardly from a back side of the cushion assembly 55. The engagement member may include detents or other retaining features to be received and retained by the first and second forwardly-extending barbed hooks 332, 334. As illustrated, the first and second forwardly-extending barbed hooks 332, 334 together generally define the coverstock securing members 120. Notably, the coverstock securing member 120 is disposed between the inner apertures 124 that extend about an upper central space 84 of the upper thoracic region 20. The inner apertures 124 provide additional breathability to the carrier 18 as a whole and also decrease the weight of the carrier 18. This, plus the elimination of mechanical fasteners, results in the entirety of the vehicle seating assembly 10 weighing less.
